The Fabrication and Transportation Characteristic of Silica Submicrometer or Nanometer One Dimension Optical Waveguide

The article introduces a new kind of method that is used to fabricate the silica sub-micrometer or nanometer one dimension optical waveguide, which has nice diameter uniformity and surface roughness. Also the base transportation characteristic of this waveguide has been described in the paper. The transmission loss is related to the diameter of the fiber and ambient refractive index because of the evanescent wave around the fiber core. The transmission loss increased sharply as the diameter of the fiber decrease or the ambient refractive index increases. This characteristic makes the kind of optical waveguide a possible application in the field of optical chemical and biochemical sensor.
